Re: Rush hour J to 9 Av

"Having the Z or J at the mercy of whatever problems happen south of the Nassau line will destroy a very well run skip stop service. I can picture 3 or 4 J's in a row because a Z is stuck somewhere in South Brooklyn."

NYCT has invested heavily into their VHF (And UHF) radio network to permit,, for example, the RCC J line dispatcher to instruct selected northbound J's to announce and make all stops to Jamaica Center. The FM radio is RCC's tactical tool at resolving a line conditions, but assumes that RCC operators are not asleep at their console.

I don't know how many Z's are run during the rush hour. If the TA plans on sending five trains south to Brooklyn, then all remaining Z line intervals can turn at Broad Street.
